According to a statement from O'Malley's office, the governor was visiting the set to showcase the expansion of the Maryland Film Tax credit and how it has improved the state economy. This fiscal year the state granted $17.5 million in credits.

The two-term governor's name is often floated as a possible contender for the 2016 Democratic presidential nomination, although he falls far behind former Secretary of State and 2008 presidential candidate Hillary Clinton in polls of probable White House contenders.

A key to any possible presidential bid by O'Malley would be what he's tried to paint as a strong economic recovery in Maryland under his leadership.
